Each piece was accompanied by a picture of the original work, and a paragraph or two about both the original and the LEGO interpretation. It also tells you how many bricks each piece took.
This one is over 75,000...

Looks cool. I entered a contest to win tix to go see that, but didn't win. I think my son would've appreciated it more if he was a couple years older, so I don't think we missed much. We did go see the Dead Sea Scrolls exhibit there a few years back. That was intense. They had a part of the prayer wall from Jerusalem on display in addition to artifacts that were 1000's of years old. You weren't even allowed to take pictures of some of the stuff because flash photography can degrade certain materials.

I don't know how other venues would be, but here that was the price if you came after 5pm. Before 5 it's a little more ($5 a ticket maybe) but that includes general admission to the entire museum as well.
